Hello, there is a software name CDRoller that can help you recover unfinalized minidvd. Only downside is that it is a paid software but if you download the trial at this link: http://www.cdroller.com/htm/dvdvideorecovery.html, it will tell you if it can recover or finalize your disk. It works by retrieving the VOB files and it can convert them into mpeg files. It is also able to make simple dvds without menu that can be played on regular DVD players.
